2 claims. (o1. 57-13s) This invention relates to a` quill nozzle and has for one of its objects the production of a simple and eflicient nozzle for forming wire rope and preforming the strands in a manner to cause the strands to fit snugly together when the rope is formed or twisted.

A further object of this invention is the production of a simple and eicient nozzle wherein the quills which preform the wire strands rest in formed channels or beds and are firmly secured in position and in parallel relation.

Other objects and advantages of the present invention will appear throughout the following specication and claims.

In the drawing- Figure 1 is an end elevational view of the quill nozzle;

Figure 2 is a longitudinal sectional view taken on line 2--2 of Figure 1;

Figure 3 is a fragmentary sectional view taken on line 3-3 of Figure 2;

Figure 4 is a sectional view of Figure 3; v

Figure 5 is a fragmentary top plan view of a portion of the nozzle showing one of the quills in position.

-By referring to the drawing, it will be seen that I0 designates the center portion of the nozzle which is provided upon the periphery thereof with longitudinally extending spaced parallel channels II, substantially circular in crosssection. Elongated quills I2, circular in crosssection, iit in the formed channels ,II so as to lie longitudinally of the channels II, as shown. These quills I2 are provided with strand-receivtaken on line 4 4 Ying spiral grooves I3 formed in the periphery thereof which spirally extend longitudinally from end to end of the quills I2 for preforming the strands I4. The spiral groove I3 of each quill I2 makes one complete turn around the quill I2, as shown. These quills I2 are anchored in pcsition against independent rotation or independent longitudinal movement relative to the head I0 by means of countersunk screws I5 which extend transversely through the quills I2 and into the head or center portion of the nozzle I0, as shown. The ends of the quills are beveled and project slightly beyond the ends of the head Iii, note Figure 2.

Filler wire quills I2a of smaller diameter than the quills I2 are placed within formed sockets or channels arranged in the center portion I0, as shown in Figure 1, and these ller wire quills I2a are interposed between the quills I2. The

quills I2EL are similar in construction to the quills 55 pass in between the I2 with the exception that they are of smaller diameter and these quills I2a are provided with spiral channels I3a similar to the channels I3.

The quills I2a are anchored in position by means of threaded screws I5*l indicated in Figure 3. It should be understood that in place of the screws which are illustrated as holding the quills in position, pins of any character may be employed which pass through the quills and t into suitable sockets formed in the center portion I0.

In place of the screws I9, suitable pins may be substituted therefor, if desired, for anchoring the quills I8 in position.

An outer sleeve I6 ts over the head I0, and this sleeve I6 is provided with a plurality of longitudinally extending spaced formed channels I1 similar to the channels II. These channels I'I are formed in the outer periphery of the sleeve I6 and the -channels I'I are preferably substantially circular in cross-section, as shown. y Quills I8 are fitted into the channels Il and are anchored in position by means of the countersunk screws |19. The quills I8 are provided with longitudinal spiral grooves 20 similar to the grooves I3 formed in the quills I2. This sleeve I6 may be anchored to the head I0 in any desired manner, such for instance as by means of a key, if desired. A retaining casing sleeve 2I fitsk over the sleeve I6 and is held in position by means of a suitable countersunk screw 22.

Any number of sleeves I6 may be tted one upon the other if desired, to form a Wire rope of a desired number of preformed strands without departing from the spirit of the invention. An important feature of the invention is the fact that the sleeve I6 may be detached and removed from the head I0 by sliding the same oif the end of the head Ill and the quills I8 may be individually removed for replacement or to facilitate access to the wires or strands which are being preformed. By removing the screws I5 the quills I2 may be individually removed after the sleeve I6 and the casing sleeve 2| are removed. The quills I8 may be individuallyy and selectively removed by simply removing the Vscrews I9 which hold the quills I8 in place. The quills I2 and I8, as Well as the sleeve I'S, may be of suitable length to suit the length of rope or cable desired;

As shown in Figure 1, the casing sleeve 2l may be formed in a pair of sections which are slightly spaced as at 2|a to permit lubricating oil to sections of the sleeve 2l and to ultimately enter the spiral grooves 20.

VThe quills may be arranged for a right and a left lay rope. Because of the structure illustrated and described, it will be seen that the quills may be easily removed to repair the strands or to replace the same, and access may be easily had to the inner quills I2 by removing the sleeve I6 and casing sleeve 2|. It should be understood that the nozzle may be used Without or with the sleeve I6, or as many sleeves may be used as desired, a suitable casing sleeve 2l of suitable size being used to t the desired diameter.

It should be understood that certain detail changes may be made without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claims..

Having described the invention, what I claim as new is:

1. A quill nozzle of the class described cornprising a head having a channel extending longitudinally of the periphery of said head, a quill tted in said channel, an anchoring element eX- tending transversely through said quill and into said periphery for anchoring the quill in a set position against independent rotation and independent longitudinal movement upon said head, and an encasing means surrounding the head and covering the quill and channel and overflying the anchoring element for preventing the accidental removal of the anchoring element while the encasing means is in place.

2. A quill nozzle of the class described comprising a head having a plurality of spaced longitudinal channels in the periphery of the head, a quill tted in each channel, an anchoring pin vfitting transversely through each quill and engaging the head for holding the quills against independent rotary and longitudinal movement relative to said head, and an encasing element snugly tting around the periphery of said head and encasing the channels and quills and also encasing the anchoring pins for preventing accidental removal of the anchoring pins While the encasing element is in place.
